Nano-sized materials are known to play important role in basic and applied sciences thus the metal and metal oxide nanoparticles have been intensively studied in the past decade [1,2]. The metal oxides particularly exhibit fascinating properties such as electronic, catalytic, magnetic and antimicrobial activity owing to their large surface area to volume ration due to a high fraction of atoms [3,4]. Zinc oxide nanoparticles have a wide band gap of 3.3 eV at room temperature and high excitation binding energy of 60 meV, which helps it to demonstrate outstanding catalytic, optical, photochemical and electronic properties [5,6]. Zinc oxide nanoparticles are known to possess unique UV filtering, antibacterial, antifungal properties also which leads to its extensive use in cosmetic and healthcare industries [7-9]. Previous studies suggest that the strong antibacterial activity of zinc oxide nanoparticles against a variety of pathogenic Gram-positive and Gram-negative bacteria attributed to its capacity of releasing Zn 2+ ion from ZnO complex and interruption of lipid bilayer integrity, ROS generation and subsequent damage to DNA and protein of the host cell [10,11]. Chemical and physical methods of nanoparticle synthesis have
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
